How Security Window Film Work

3M Safety & Security Window Film is already protecting businesses, schools and homes across the country. Here’s how they work:

  • The film and its strong adhesive form a protective membrane on the glass.
  • The film is applied on the interior side of the window, which protects it from the elements and from direct attacks.
  • While the film doesn’t protect the glass from breaking, it does help hold together the broken glass fragments.
  • Film attachment systems are applied along the perimeter to anchor the film to the window frame.
  • The film forces an intruder to create an opening through the center of the broken glass, which slows them down by up to 2 minutes and gives responders precious time.

3M Safety & Security Window Films provide:

  • A deterrent against smash-and-grab burglars
  • Safety glazing
  • Seismic preparedness
  • Protection against spontaneous glass breakage
  • Blast mitigation
